eMMC is storage. If you really cleared all of it, you have to flash the ROM again and, depending on the phone, a recovery.
Please join the Android Central community so you can continue the discussion here. How did you "clear eMMC"? There's no function in the phone for that. Do you mean a factory reset? If so, you have to start over as if the phone were new - enter everything, install apps (and I hope you have everything backed up, because any music, pictures, etc., are gone).
